December 14 ------ On June 26, 2025 right around the corner the International Maritime Organization's (IMO) Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships (Hong Kong Convention) will enter into force. This landmark agreement is crucial for ensuring that the ship recycling industry operates safely and sustainably, aiming to protect both workers and the environment from the dangers posed by hazardous materials on ships. Without proper management, hazardous materials can lead to acute and chronic illness as well as environmental pollution, including oil spills, leakage of toxic substances, and contamination of soil and water. These issues can harm marine life, local ecosystems, and even drinking water supplies.
Each year, approximately 500 ocean-going commercial vessels reach the end of their service life and undergo the process of shipbreaking (i.e., the dismantling of ships for recycling). In accordance with the HKC, vessels over 500 gross tonnage (GT) are required to maintain an Inventory of Hazardous Materials (IHM). This inventory details all hazardous substances on board, such as asbestos and heavy metals, thereby enabling safe and compliant handling and disposal during the ship dismantling process.
As the HKC comes into force, all ships greater than 500 GT will need to have an IHM prepared and approved by the date of implementation. This requirement applies to vessels flagged under countries that are parties to the HKC, and flag Administrators are expected to enforce adherence to it. The HKC outlines specific hazardous materials that must be inventoried and managed, including asbestos, heavy metals, chromium-6, and polychlorinated biphenyls (PCBs). Proper identification and handling of these substances will mitigate the risks associated with their disposal during recycling.
Regrettably, the history of ship recycling has been marred by numerous accidents. These incidents highlight the urgent need for stringent safety measures and compliance with regulations stipulated by the HKC. The IHM, integral to the HKC, plays a crucial role in mitigating risks associated with hazardous materials. It establishes best practices widely accepted in the shipping and recycling industries. IHM inventories should be conducted at various stages of a ship’s life:
• Approval and Certification (PART I): Initial inventory creation
• Maintenance and Renewal: Regular updates every five years
• Dismantling and Recycling (PART II and III): Final inventory management during the recycling process.
Experienced hazardous materials (HAZMAT) certified inspectors carry out these assessments and can guide shipowners on compliance. If hazardous materials are identified, remediation can be implemented under expert supervision, including the removal and replacement with non-hazardous alternatives.
As the HKC approaches its enforcement date, it represents a leap forward in improving the safety of ship recycling processes and protecting both workers and the marine environment. By ensuring all vessels possess a comprehensive IHM, the maritime industry can foster a safer, more responsible approach to ship disposal, ultimately benefiting society at large. Monitoring hazardous materials throughout a ship's lifecycle is essential for minimizing health risks and adhering to environmental regulations. The HKC, together with the implementation of IHM, underscores the commitment of the shipping industry to sustainable practices and the well-being of communities worldwide.
